CARTRIDGE.

SPECIFICATION forming part of Letters Patent No. 503,096, dated August8, 1893.

Application led February 2, 1898. Serial No. 460,679. (No model.):Patented in Germany April 29, 1892, No. 7.428, and in Belgium September7, 1892, No. 101,255.

To all whom it may concern:

Be it known that I, FREDERIK MOHR, a subject of the King of Prussia, anda resident of Magdeburg, in the Kingdom of Prussia, German Empire, haveinvented new and useful Improvementsin Cartridges, (for which I havereceived Letters Patent in Germany; dated April 29, 1892, No. 7,428, andin Belgium, dated September '7, 1892, No. l0l,255,) of

io which the following is a specification.

This invention relates to cartridges and has for its object to providean easily portable and cheap ammunition for held guns with quick-firingbreech blocks and for tire-arms wherein the charge is required to besometimes large and sometimes small.

It is well-known that projectiles firmly connected with metalliccartridge cases permit of quickly loading the gun; the cases form zomoreover an excellent packing, inasmuch as the powder gases press thewall of the case against the wall of the gun; and lastly the ignitingapparatus, consisting of an igniting cap, is extremely simple. Fromthese advantages possessed by the above characterized ammunition thereresults very material advantages in the arrangements of the breechmechanism of the gun. If however a gun is to be used for alternatelytiring with larger or smaller charges,such for instance as takes placein the case of mortars and howitzers, the connection of the projectilewith the cartridge case must be abandoned because it is impracticable toprepare a great number of cartridges suited for the various rangesrequired. Nevertheless the advantages afforded by metallic cartridgesare so important that it has been desired to use such cartridges forvarying charges. This problem is solved by the present invention whereina bag is employed to contain the charge, said bag being rmly connectedto a metallic cartridge case either before or after it is filled.

In the accompanying drawings which illustrate the invention, Figure l isa side view partly in section of a cartridge. Fig. 2 shows a slightmodification in construction.

a is the base of the metallic case.

c is the bag for containing the charge.

A very simple and reliable mode of con necting the bag to the metalliccase is that hereinafter described. On the inner side of the cylindricalpart of the metallic case in proximity to the base a is formed anannular collar or shoulder b which may be solid as shown in Fig. l, ormay be formed by contracting the wall of the case as shown in Fig.

2. In the bottom of the cartridge bag c is placed according to oneconstruction a fiat or slightly arched rigid plate d of pasteboard, 6owood, metal or other suitable material the outer edge e of which is bentas shown to form a spring. The fiat central part of the plate CZ may bereinforced by another plate CZ placed thereon to give the desiredrigidity at that part, while retaining sufficient spring at the curvedpart e for the object in view. When the cartridge bag is pressed intothe cartridge case the edge e oi the plate d, as it passes the collar orshoulder b, is bent inward but as 7o soon as it has moved behind thesaid shoulder, the said curved edge springs out again and bears with itsedge against the lower face of the shoulder and locks the bag and casetogether. Sometimes according to this invention the locking piece d ismade of very elastic material, such as india-rubber, cork or the likeand in such case the curved or turned-up edge is not required. Theentire plate will be compressed a little on forcing itthrough the 8oannular collar b and will expand again and lock the bag to the metalliccase as soon as it has passed the said collar.

In order to relieve a little the pressure on the plate d, the upper edgeh of the case may be bent inward as shown to help to hold the bag. Theplate d may at the same time be made to serve as a support for the capt' which contains the priming interposed between the igniting cap if.,arranged in the base u, of the 9o case, and the charge Z.

The described connection between the bag and. metallic case is verysecure and will not admit of separating the two without tearing the bag.It is the form of connection which is preferred according to thisinvention but it is obvious that the details of such connection may bemodified without departing from the nature of this invention.

The problem of using metallic cartridge roo cases for varying charges issolved in a satisfactory manner by the herein described combination of abag cartridge With a cartridge case. The metallic casings with ignitingcaps 5 can be produced almost as cheaply as the ordinary tubes.

Vhat I do claim as my invention, and desire to secure by Letters Patent,is-

1. A cartridge composed of a bag contain- Io ing the charge, and ametallic case; the case purpose set forth.

2. In a cartridge, the combination of a nietallic shellhaving a shoulderextending transversely within it, and a bag containing the charge, andprovided with an elastic iiexible 2o attaching disk, arranged to becompressed in forcing past the shoulder and to then expand behind it tounite the parts of the cartridge, as explained.

3. A cartridge, consisting of the metallic case, formed with the innertransverse shoulder, and a bag containing the charge provided With theattaching disk, concaved to make it elastic at the edge whereby it isadapted to be forced past the shoulder and expand to engage behind theshoulder, as explained.

4. In a cartridge, the combination 0f the metallic shell having theinner transverse shoulder', and the charge-bag having the attachingdisk, concaved for operation as eX- plained and supplemented by thereinforce disk, all substantially as and for the purpose set forth.
